ABSTRACT

An UE transmits at least one UE configuration parameter to a base station comprising at least one preferred parameter for a UE configuration, e.g., in addition to a preferred setting for a delay budget report. The UE then receives a configuration from the base station based, at least in part, on the at least one UE configuration parameter transmitted to the base station. Additionally, a base station receives the at least one UE configuration parameter from a UE comprising at least one preferred parameter for a UE configuration, e.g., in addition to a preferred setting for a delay budget report. The base station then configures the UE using the at least one UE configuration parameter received from the UE.

BACKGROUND Technical Field

The present disclosure relates generally to communication systems, andmore particularly, to a communication between a User Equipment (UE) anda base station.

INTRODUCTION

Wireless communication systems are widely deployed to provide varioustelecommunication services such as telephony, video, data, messaging,and broadcasts. Typical wireless communication systems may employmultiple-access technologies capable of supporting communication withmultiple users by sharing available system resources. Examples of suchmultiple-access technologies include code division multiple access(CDMA) systems, time division multiple access (TDMA) systems, frequencydivision multiple access (FDMA) systems, orthogonal frequency divisionmultiple access (OFDMA) systems, single-carrier frequency divisionmultiple access (SC-FDMA) systems, and time division synchronous codedivision multiple access (TD-SCDMA) systems.

These multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent wireless devices to communicate on a municipal, national,regional, and even global level. An example telecommunication standardis 5G New Radio (NR). 5G NR is part of a continuous mobile broadbandevolution promulgated by Third Generation Partnership Project (3GPP) tomeet new requirements associated with latency, reliability, security,scalability (e.g., with Internet of Things (IoT)), and otherrequirements. 5G NR includes services associated with enhanced mobilebroadband (eMBB), massive machine type communications (mMTC), and ultrareliable low latency communications (URLLC). Some aspects of 5G NR maybe based on the 4G Long Term Evolution (LTE) standard. There exists aneed for further improvements in 5G NR technology. These improvementsmay also be applicable to other multi-access technologies and thetelecommunication standards that employ these technologies.

DETAILED DESCRIPTION

The detailed description set forth below in connection with the appendeddrawings is intended as a description of various configurations and isnot intended to represent the only configurations in which the conceptsdescribed herein may be practiced. The detailed description includesspecific details for the purpose of providing a thorough understandingof various concepts. However, it will be apparent to those skilled inthe art that these concepts may be practiced without these specificdetails. In some instances, well known structures and components areshown in block diagram form in order to avoid obscuring such concepts.

A network may control many aspects of the radio configurations for a UE.However, a UE has a better understanding of various factors than thebase station. For example, the UE is aware of a power status, e.g.,including an anticipated battery life. The UE is also aware of userchanges to power preferences, e.g., when a user switches to a low powermode in a user menu at the UE. A UE may also be aware that anapplication is active or is anticipated to be active. Aspects presentedherein enable a network to make more effective radio configurations fora particular UE by having the UE share information about the UE,including recommendations and/or preferences, with the base station. Forexample, the UE may provide recommendations/preferences regarding theUE's preferred radio configurations based on information known at the UEthat is not known by the base station. The base station may thendetermine radio configurations for the UE based on an increasedunderstanding of factors and preferences for the UE.

Several aspects of telecommunication systems will now be presented withreference to various apparatus and methods. These apparatus and methodswill be described in the following detailed description and illustratedin the accompanying drawings by various blocks, components, circuits,processes, algorithms, etc. (collectively referred to as “elements”).These elements may be implemented using electronic hardware, computersoftware, or any combination thereof. Whether such elements areimplemented as hardware or software depends upon the particularapplication and design constraints imposed on the overall system.

By way of example, an element, or any portion of an element, or anycombination of elements may be implemented as a “processing system” thatincludes one or more processors. Examples of processors includemicroprocessors, microcontrollers, graphics processing units (GPUs),central processing units (CPUs), application processors, digital signalprocessors (DSPs), reduced instruction set computing (RISC) processors,systems on a chip (SoC), baseband processors, field programmable gatearrays (FPGAs), programmable logic devices (PLDs), state machines, gatedlogic, discrete hardware circuits, and other suitable hardwareconfigured to perform the various functionality described throughoutthis disclosure. One or more processors in the processing system mayexecute software. Software shall be construed broadly to meaninstructions, instruction sets, code, code segments, program code,programs, subprograms, software components, applications, softwareapplications, software packages, routines, subroutines, objects,executables, threads of execution, procedures, functions, etc., whetherreferred to as software, firmware, middleware, microcode, hardwaredescription language, or otherwise.

Accordingly, in one or more example aspects, the functions described maybe implemented in hardware, software, or any combination thereof. Ifimplemented in software, the functions may be stored on or encoded asone or more instructions or code on a computer-readable medium.Computer-readable media includes computer storage media. Storage mediamay be any available media that can be accessed by a computer. By way ofexample, and not limitation, such computer-readable media can comprise arandom-access memory (RAM), a read-only memory (ROM), an electricallyerasable programmable ROM (EEPROM), optical disk storage, magnetic diskstorage, other magnetic storage devices, combinations of theaforementioned types of computer-readable media, or any other mediumthat can be used to store computer executable code in the form ofinstructions or data structures that can be accessed by a computer.

FIG. 1 is a diagram illustrating an example of a wireless communicationssystem and an access network 100. The wireless communications system(also referred to as a wireless wide area network (WWAN)) includes basestations 102, UEs 104, an Evolved Packet Core (EPC) 160, and a 5G Core(5GC) 190. The base stations 102 may include macro cells (high powercellular base station) and/or small cells (low power cellular basestation). The macro cells include base stations. The small cells includefemtocells, picocells, and microcells.

The base stations 102 configured for 4G LTE (collectively referred to asEvolved Universal Mobile Telecommunications System (UMTS) TerrestrialRadio Access Network (E-UTRAN)) may interface with the EPC 160 throughbackhaul links 132 (e.g., Si interface). The base stations 102configured for 5G NR (collectively referred to as Next Generation RAN(NG-RAN)) may interface with 5GC 190 through backhaul links 184. Inaddition to other functions, the base stations 102 may perform one ormore of the following functions: transfer of user data, radio channelciphering and deciphering, integrity protection, header compression,mobility control functions (e.g., handover, dual connectivity),inter-cell interference coordination, connection setup and release, loadbalancing, distribution for non-access stratum (NAS) messages, NAS nodeselection, synchronization, radio access network (RAN) sharing,multimedia broadcast multicast service (MBMS), subscriber and equipmenttrace, RAN information management (RIM), paging, positioning, anddelivery of warning messages. The base stations 102 may communicatedirectly or indirectly (e.g., through the EPC 160 or 5GC 190) with eachother over backhaul links 134 (e.g., X2 interface). The backhaul links134 may be wired or wireless.

The base stations 102 may wirelessly communicate with the UEs 104. Eachof the base stations 102 may provide communication coverage for arespective geographic coverage area 110. There may be overlappinggeographic coverage areas 110. For example, the small cell 102′ may havea coverage area 110′ that overlaps the coverage area 110 of one or moremacro base stations 102. A network that includes both small cell andmacro cells may be known as a heterogeneous network. A heterogeneousnetwork may also include Home Evolved Node Bs (eNBs) (HeNBs), which mayprovide service to a restricted group known as a closed subscriber group(CSG). The communication links 120 between the base stations 102 and theUEs 104 may include uplink (UL) (also referred to as reverse link)transmissions from a UE 104 to a base station 102 and/or downlink (DL)(also referred to as forward link) transmissions from a base station 102to a UE 104. The communication links 120 may use multiple-input andmultiple-output (MIMO) antenna technology, including spatialmultiplexing, beamforming, and/or transmit diversity. The communicationlinks may be through one or more carriers. The base stations 102/UEs 104may use spectrum up to Y MHz (e.g., 5, 10, 15, 20, 100, 400, etc. MHz)bandwidth per carrier allocated in a carrier aggregation of up to atotal of Yx MHz (x component carriers) used for transmission in eachdirection. The carriers may or may not be adjacent to each other.Allocation of carriers may be asymmetric with respect to DL and UL(e.g., more or less carriers may be allocated for DL than for UL). Thecomponent carriers may include a primary component carrier and one ormore secondary component carriers. A primary component carrier may bereferred to as a primary cell (PCell) and a secondary component carriermay be referred to as a secondary cell (SCell).

Certain UEs 104 may communicate with each other using device-to-device(D2D) communication link 158. The D2D communication link 158 may use theDL/UL WWAN spectrum. The D2D communication link 158 may use one or moresidelink channels, such as a physical sidelink broadcast channel(PSBCH), a physical sidelink discovery channel (PSDCH), a physicalsidelink shared channel (PSSCH), and a physical sidelink control channel(PSCCH). D2D communication may be through a variety of wireless D2Dcommunications systems, such as for example, FlashLinQ, WiMedia,Bluetooth, ZigBee, Wi-Fi based on the IEEE 802.11 standard, LTE, or NR.

The wireless communications system may further include a Wi-Fi accesspoint (AP) 150 in communication with Wi-Fi stations (STAs) 152 viacommunication links 154 in a 5 GHz unlicensed frequency spectrum. Whencommunicating in an unlicensed frequency spectrum, the STAs 152/AP 150may perform a clear channel assessment (CCA) prior to communicating inorder to determine whether the channel is available.

The small cell 102′ may operate in a licensed and/or an unlicensedfrequency spectrum. When operating in an unlicensed frequency spectrum,the small cell 102′ may employ NR and use the same 5 GHz unlicensedfrequency spectrum as used by the Wi-Fi AP 150. The small cell 102′,employing NR in an unlicensed frequency spectrum, may boost coverage toand/or increase capacity of the access network. A base station 102,whether a small cell 102′ or a large cell (e.g., macro base station),may include an eNB, gNodeB (gNB), or other type of base station. Somebase stations 180, such as a gNB, may operate in a traditional sub 6 GHzspectrum, in millimeter wave (mmW) frequencies, and/or near mmWfrequencies in communication with the UE 104. When a base station 180,such as a gNB, operates in mmW or near mmW frequencies, the base station180 may be referred to as an mmW base station. Extremely high frequency(EHF) is part of the RF in the electromagnetic spectrum. EHF has a rangeof 30 GHz to 300 GHz and a wavelength between 1 millimeter and 10millimeters. Radio waves in the band may be referred to as a millimeterwave. Near mmW may extend down to a frequency of 3 GHz with a wavelengthof 100 millimeters. The super high frequency (SHF) band extends between3 GHz and 30 GHz, also referred to as centimeter wave. Communicationsusing the mmW/near mmW radio frequency band has extremely high path lossand a short range. The mmW base station, e.g., base station 180, mayutilize beamforming 182 with the UE 104 to compensate for the extremelyhigh path loss and short range.

The base station 180 may transmit a beamformed signal to the UE 104 inone or more transmit directions 182′. The UE 104 may receive thebeamformed signal from the base station 180 in one or more receivedirections 182″. The UE 104 may also transmit a beamformed signal to thebase station 180 in one or more transmit directions. The base station180 may receive the beamformed signal from the UE 104 in one or morereceive directions. The base station 180/UE 104 may perform beamtraining to determine the best receive and transmit directions for eachof the base station 180/UE 104. The transmit and receive directions forthe base station 180 may or may not be the same. The transmit andreceive directions for the UE 104 may or may not be the same.

The EPC 160 may include a Mobility Management Entity (MME) 162, otherMMEs 164, a Serving Gateway 166, a Multimedia Broadcast MulticastService (MBMS) Gateway 168, a Broadcast Multicast Service Center (BM-SC)170, and a Packet Data Network (PDN) Gateway 172. The MME 162 may be incommunication with a Home Subscriber Server (HSS) 174. The MME 162 isthe control node that processes the signaling between the UEs 104 andthe EPC 160. Generally, the MME 162 provides bearer and connectionmanagement. All user Internet protocol (IP) packets are transferredthrough the Serving Gateway 166, which itself is connected to the PDNGateway 172. The PDN Gateway 172 provides UE IP address allocation aswell as other functions. The PDN Gateway 172 and the BM-SC 170 areconnected to the IP Services 176. The IP Services 176 may include theInternet, an intranet, an IP Multimedia Subsystem (IMS), a PS StreamingService, and/or other IP services. The BM-SC 170 may provide functionsfor MBMS user service provisioning and delivery. The BM-SC 170 may serveas an entry point for content provider MBMS transmission, may be used toauthorize and initiate MBMS Bearer Services within a public land mobilenetwork (PLMN), and may be used to schedule MBMS transmissions. The MBMSGateway 168 may be used to distribute MBMS traffic to the base stations102 belonging to a Multicast Broadcast Single Frequency Network (MBSFN)area broadcasting a particular service, and may be responsible forsession management (start/stop) and for collecting eMBMS relatedcharging information.

The 5GC 190 may include a Access and Mobility Management Function (AMF)192, other AMFs 193, a Session Management Function (SMF) 194, and a UserPlane Function (UPF) 195. The AMF 192 may be in communication with aUnified Data Management (UDM) 196. The AMF 192 is the control node thatprocesses the signaling between the UEs 104 and the 5GC 190. Generally,the AMF 192 provides QoS flow and session management. All user Internetprotocol (IP) packets are transferred through the UPF 195. The UPF 195provides UE IP address allocation as well as other functions. The UPF195 is connected to the IP Services 197. The IP Services 197 may includethe Internet, an intranet, an IP Multimedia Subsystem (IMS), a PSStreaming Service, and/or other IP services.

The base station may also be referred to as a gNB, Node B, evolved NodeB (eNB), an access point, a base transceiver station, a radio basestation, a radio transceiver, a transceiver function, a basic serviceset (BSS), an extended service set (ESS), a transmit reception point(TRP), or some other suitable terminology. The base station 102 providesan access point to the EPC 160 or 5GC 190 for a UE 104. Examples of UEs104 include a cellular phone, a smart phone, a session initiationprotocol (SIP) phone, a laptop, a personal digital assistant (PDA), asatellite radio, a global positioning system, a multimedia device, avideo device, a digital audio player (e.g., MP3 player), a camera, agame console, a tablet, a smart device, a wearable device, a vehicle, anelectric meter, a gas pump, a large or small kitchen appliance, ahealthcare device, an implant, a sensor/actuator, a display, or anyother similar functioning device. Some of the UEs 104 may be referred toas IoT devices (e.g., parking meter, gas pump, toaster, vehicles, heartmonitor, etc.). The UE 104 may also be referred to as a station, amobile station, a subscriber station, a mobile unit, a subscriber unit,a wireless unit, a remote unit, a mobile device, a wireless device, awireless communications device, a remote device, a mobile subscriberstation, an access terminal, a mobile terminal, a wireless terminal, aremote terminal, a handset, a user agent, a mobile client, a client, orsome other suitable terminology.

Referring again to FIG. 1, in certain aspects, the UE 104 may include anassistance information component 198 configured to transmit UEconfiguration parameter(s) to base station 102/180 comprising at leastone preferred parameter for a UE configuration, e.g., in addition to apreferred setting for a delay budget report and/or to receives aconfiguration from the base station based, at least in part, on the UEconfiguration parameter(s) transmitted to the base station 102/180.Similarly, the base station 102/180 may comprise an assistanceinformation component 199 configured to receive UE configurationparameter(s) from UE 104 comprising at least one preferred parameter fora UE configuration, e.g., in addition to a preferred setting for a delaybudget report and/or to configure the UE using the UE configurationparameter(s) received from the UE 104. Although examples may be focusedon 5G NR, the concepts described herein may be applicable to othersimilar areas, such as LTE, LTE-A, CDMA, GSM, and other wirelesstechnologies.

FIG. 2A is a diagram 200 illustrating an example of a first subframewithin a 5G/NR frame structure. FIG. 2B is a diagram 230 illustrating anexample of DL channels within a 5G/NR subframe. FIG. 2C is a diagram 250illustrating an example of a second subframe within a 5G/NR framestructure. FIG. 2D is a diagram 280 illustrating an example of ULchannels within a 5G/NR subframe. The 5G/NR frame structure may be FDDin which for a particular set of subcarriers (carrier system bandwidth),subframes within the set of subcarriers are dedicated for either DL orUL, or may be TDD in which for a particular set of subcarriers (carriersystem bandwidth), subframes within the set of subcarriers are dedicatedfor both DL and UL. In the examples provided by FIGS. 2A, 2C, the 5G/NRframe structure is assumed to be TDD, with subframe 4 being configuredwith slot format 28 (with mostly DL), where D is DL, U is UL, and X isflexible for use between DL/UL, and subframe 3 being configured withslot format 34 (with mostly UL). While subframes 3, 4 are shown withslot formats 34, 28, respectively, any particular subframe may beconfigured with any of the various available slot formats 0-61. Slotformats 0, 1 are all DL, UL, respectively. Other slot formats 2-61include a mix of DL, UL, and flexible symbols. UEs are configured withthe slot format (dynamically through DL control information (DCI), orsemi-statically/statically through radio resource control (RRC)signaling) through a received slot format indicator (SFI). Note that thedescription infra applies also to a 5G/NR frame structure that is TDD.

Other wireless communication technologies may have a different framestructure and/or different channels. A frame (10 ms) may be divided into10 equally sized subframes (1 ms). Each subframe may include one or moretime slots. Subframes may also include mini-slots, which may include 7,4, or 2 symbols. Each slot may include 7 or 14 symbols, depending on theslot configuration. For slot configuration 0, each slot may include 14symbols, and for slot configuration 1, each slot may include 7 symbols.The symbols on DL may be cyclic prefix (CP) OFDM (CP-OFDM) symbols. Thesymbols on UL may be CP-OFDM symbols (for high throughput scenarios) ordiscrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbols (alsoreferred to as single carrier frequency-division multiple access(SC-FDMA) symbols) (for power limited scenarios; limited to a singlestream transmission). The number of slots within a subframe is based onthe slot configuration and the numerology. For slot configuration 0,different numerologies μ0 to 5 allow for 1, 2, 4, 8, 16, and 32 slots,respectively, per subframe. For slot configuration 1, differentnumerologies 0 to 2 allow for 2, 4, and 8 slots, respectively, persubframe. Accordingly, for slot configuration 0 and numerology μ, thereare 14 symbols/slot and 2^(μ) slots/subframe. The subcarrier spacing andsymbol length/duration are a function of the numerology. The subcarrierspacing may be equal to 2^(μ)*15 kKz, where μ is the numerology 0 to 5.As such, the numerology μ=0 has a subcarrier spacing of 15 kHz and thenumerology μ=5 has a subcarrier spacing of 480 kHz. The symbollength/duration is inversely related to the subcarrier spacing. FIGS.2A-2D provide an example of slot configuration 0 with 14 symbols perslot and numerology μ=0 with 1 slot per subframe. The subcarrier spacingis 15 kHz and symbol duration is approximately 66.7 μs.

A resource grid may be used to represent the frame structure. Each timeslot includes a resource block (RB) (also referred to as physical RBs(PRBs)) that extends 12 consecutive subcarriers. The resource grid isdivided into multiple resource elements (REs). The number of bitscarried by each RE depends on the modulation scheme.

As illustrated in FIG. 2A, some of the REs carry reference (pilot)signals (RS) for the UE. The RS may include demodulation RS (DM-RS)(indicated as R_(x) for one particular configuration, where 100 x is theport number, but other DM-RS configurations are possible) and channelstate information reference signals (CSI-RS) for channel estimation atthe UE. The RS may also include beam measurement RS (BRS), beamrefinement RS (BRRS), and phase tracking RS (PT-RS).

FIG. 2B illustrates an example of various DL channels within a subframeof a frame. The physical downlink control channel (PDCCH) carries DCIwithin one or more control channel elements (CCEs), each CCE includingnine RE groups (REGs), each REG including four consecutive REs in anOFDM symbol. A primary synchronization signal (PSS) may be within symbol2 of particular subframes of a frame. The PSS is used by a UE 104 todetermine subframe/symbol timing and a physical layer identity. Asecondary synchronization signal (SSS) may be within symbol 4 ofparticular subframes of a frame. The SSS is used by a UE to determine aphysical layer cell identity group number and radio frame timing. Basedon the physical layer identity and the physical layer cell identitygroup number, the UE can determine a physical cell identifier (PCI).Based on the PCI, the UE can determine the locations of theaforementioned DM-RS. The physical broadcast channel (PBCH), whichcarries a master information block (MIB), may be logically grouped withthe PSS and SSS to form a synchronization signal (SS)/PBCH block. TheMIB provides a number of RBs in the system bandwidth and a system framenumber (SFN). The physical downlink shared channel (PDSCH) carries userdata, broadcast system information not transmitted through the PBCH suchas system information blocks (SIBs), and paging messages.

As illustrated in FIG. 2C, some of the REs carry DM-RS (indicated as Rfor one particular configuration, but other DM-RS configurations arepossible) for channel estimation at the base station. The UE maytransmit DM-RS for the physical uplink control channel (PUCCH) and DM-RSfor the physical uplink shared channel (PUSCH). The PUSCH DM-RS may betransmitted in the first one or two symbols of the PUSCH. The PUCCHDM-RS may be transmitted in different configurations depending onwhether short or long PUCCHs are transmitted and depending on theparticular PUCCH format used. Although not shown, the UE may transmitsounding reference signals (SRS). The SRS may be used by a base stationfor channel quality estimation to enable frequency-dependent schedulingon the UL.

FIG. 2D illustrates an example of various UL channels within a subframeof a frame. The PUCCH may be located as indicated in one configuration.The PUCCH carries uplink control information (UCI), such as schedulingrequests, a channel quality indicator (CQI), a precoding matrixindicator (PMI), a rank indicator (RI), and HARQ ACK/NACK feedback. ThePUSCH carries data, and may additionally be used to carry a bufferstatus report (BSR), a power headroom report (PHR), and/or UCI.

FIG. 3 is a block diagram of a base station 310 in communication with aUE 350 in an access network. In the DL, IP packets from the EPC 160 maybe provided to a controller/processor 375. The controller/processor 375implements layer 3 and layer 2 functionality. Layer 3 includes a radioresource control (RRC) layer, and layer 2 includes a packet dataconvergence protocol (PDCP) layer, a radio link control (RLC) layer, anda medium access control (MAC) layer. The controller/processor 375provides RRC layer functionality associated with broadcasting of systeminformation (e.g., MIB, SIBs), RRC connection control (e.g., RRCconnection paging, RRC connection establishment, RRC connectionmodification, and RRC connection release), inter radio access technology(RAT) mobility, and measurement configuration for UE measurementreporting; PDCP layer functionality associated with headercompression/decompression, security (ciphering, deciphering, integrityprotection, integrity verification), and handover support functions; RLClayer functionality associated with the transfer of upper layer packetdata units (PDUs), error correction through ARQ, concatenation,segmentation, and reassembly of RLC service data units (SDUs),re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; andMAC layer functionality associated with mapping between logical channelsand transport channels, multiplexing of MAC SDUs onto transport blocks(TBs), demultiplexing of MAC SDUs from TBs, scheduling informationreporting, error correction through HARQ, priority handling, and logicalchannel prioritization. In certain aspects, the base station 310 maycomprise an assistance information component 399 configured to receiveUE configuration parameter(s) from UE 350 comprising at least onepreferred parameter for a UE configuration, e.g., in addition to apreferred setting for a delay budget report and/or to configure the UEusing the UE configuration parameter(s) received from the UE 350.

The transmit (TX) processor 316 and the receive (RX) processor 370implement layer 1 functionality associated with various signalprocessing functions. Layer 1, which includes a physical (PHY) layer,may include error detection on the transport channels, forward errorcorrection (FEC) coding/decoding of the transport channels,interleaving, rate matching, mapping onto physical channels,modulation/demodulation of physical channels, and MIMO antennaprocessing. The TX processor 316 handles mapping to signalconstellations based on various modulation schemes (e.g., binaryphase-shift keying (BPSK), quadrature phase-shift keying (QPSK),M-phase-shift keying (M-PSK), M-quadrature amplitude modulation(M-QAM)). The coded and modulated symbols may then be split intoparallel streams. Each stream may then be mapped to an OFDM subcarrier,multiplexed with a reference signal (e.g., pilot) in the time and/orfrequency domain, and then combined together using an Inverse FastFourier Transform (IFFT) to produce a physical channel carrying a timedomain OFDM symbol stream. The OFDM stream is spatially precoded toproduce multiple spatial streams. Channel estimates from a channelestimator 374 may be used to determine the coding and modulation scheme,as well as for spatial processing. The channel estimate may be derivedfrom a reference signal and/or channel condition feedback transmitted bythe UE 350. Each spatial stream may then be provided to a differentantenna 320 via a separate transmitter 318TX. Each transmitter 318TX maymodulate an RF carrier with a respective spatial stream fortransmission.

At the UE 350, each receiver 354RX receives a signal through itsrespective antenna 352. Each receiver 354RX recovers informationmodulated onto an RF carrier and provides the information to the receive(RX) processor 356. The TX processor 368 and the RX processor 356implement layer 1 functionality associated with various signalprocessing functions. The RX processor 356 may perform spatialprocessing on the information to recover any spatial streams destinedfor the UE 350. If multiple spatial streams are destined for the UE 350,they may be combined by the RX processor 356 into a single OFDM symbolstream. The RX processor 356 then converts the OFDM symbol stream fromthe time-domain to the frequency domain using a Fast Fourier Transform(FFT). The frequency domain signal comprises a separate OFDM symbolstream for each subcarrier of the OFDM signal. The symbols on eachsubcarrier, and the reference signal, are recovered and demodulated bydetermining the most likely signal constellation points transmitted bythe base station 310. These soft decisions may be based on channelestimates computed by the channel estimator 358. The soft decisions arethen decoded and deinterleaved to recover the data and control signalsthat were originally transmitted by the base station 310 on the physicalchannel. The data and control signals are then provided to thecontroller/processor 359, which implements layer 3 and layer 2functionality.

The controller/processor 359 can be associated with a memory 360 thatstores program codes and data. The memory 360 may be referred to as acomputer-readable medium. In the UL, the controller/processor 359provides demultiplexing between transport and logical channels, packetreassembly, deciphering, header decompression, and control signalprocessing to recover IP packets from the EPC 160. Thecontroller/processor 359 is also responsible for error detection usingan ACK and/or NACK protocol to support HARQ operations.

Similar to the functionality described in connection with the DLtransmission by the base station 310, the controller/processor 359provides RRC layer functionality associated with system information(e.g., MIB, SIBs) acquisition, RRC connections, and measurementreporting; PDCP layer functionality associated with headercompression/decompression, and security (ciphering, deciphering,integrity protection, integrity verification); RLC layer functionalityassociated with the transfer of upper layer PDUs, error correctionthrough ARQ, concatenation, segmentation, and reassembly of RLC SDUs,re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; andMAC layer functionality associated with mapping between logical channelsand transport channels, multiplexing of MAC SDUs onto TBs,demultiplexing of MAC SDUs from TBs, scheduling information reporting,error correction through HARQ, priority handling, and logical channelprioritization. In certain aspects, the UE 350 may include an assistanceinformation component 398 configured to transmit UE configurationparameter(s) to base station 310 comprising at least one preferredparameter for a UE configuration, e.g., in addition to a preferredsetting for a delay budget report and/or to receives a configurationfrom the base station based, at least in part, on the UE configurationparameter(s) transmitted to the base station 310.

Channel estimates derived by a channel estimator 358 from a referencesignal or feedback transmitted by the base station 310 may be used bythe TX processor 368 to select the appropriate coding and modulationschemes, and to facilitate spatial processing. The spatial streamsgenerated by the TX processor 368 may be provided to different antenna352 via separate transmitters 354TX. Each transmitter 354TX may modulatean RF carrier with a respective spatial stream for transmission.

The UL transmission is processed at the base station 310 in a mannersimilar to that described in connection with the receiver function atthe UE 350. Each receiver 318RX receives a signal through its respectiveantenna 320. Each receiver 318RX recovers information modulated onto anRF carrier and provides the information to a RX processor 370.

The controller/processor 375 can be associated with a memory 376 thatstores program codes and data. The memory 376 may be referred to as acomputer-readable medium. In the UL, the controller/processor 375provides demultiplexing between transport and logical channels, packetreassembly, deciphering, header decompression, control signal processingto recover IP packets from the UE 350. IP packets from thecontroller/processor 375 may be provided to the EPC 160. Thecontroller/processor 375 is also responsible for error detection usingan ACK and/or NACK protocol to support HARQ operations.

A network may control many aspects of the radio configurations for a UE.However, a UE has a better understanding of some factors than the basestation. For example, the UE is aware of the UE's power status, e.g.,including an anticipated battery life. The UE is also aware of userchanges to power preferences, e.g., when a user switches to a low powermode in a user menu at the UE. A UE may also be aware that anapplication is active or is anticipated to be active. Aspects presentedherein enable a network to make more effective radio configurations fora particular UE by having the UE share information about the UE,including recommendations and/or preferences, with the base station. Forexample, the UE may provide recommendations regarding preferred radioconfiguration parameters based on information known at the UE that isnot known by the base station. The base station may then determine radioconfigurations for the UE based on an increased understanding of factorsand preferences for the UE.

FIG. 4 illustrates an example communication flow 400 between a basestation 402 and a UE 404 in accordance with the aspects presentedherein. As illustrated at 407, the UE 404 may select parameters forradio configurations for the UE. The selection may be based on differentpurposes. The UE 404 may classify UE configuration parameters intodifferent categories based on different purposes or user preferences.One example purpose may be a power saving purpose. Other examples ofpurposes may include performance, improved communication, etc. Forexample, the UE 404 may signal certain DRX parameters when the UEmeasures traffic patterns and estimates an optimal set of DRX parametersbased on the measured traffic. As another example, the UE 404 may signalbeam management parameters when the UE 404 will adjust its receivingbeam or transmission beam. Thus, the selected parameters may correspondto preferences or recommendations from the UE 404 for UE radioparameters. At 409, the UE may indicate the selected parameters, from405, to the base station 402. The selected parameters/UE preferences forradio configurations may be referred to as assistance information, suchas UE assistance information and may include UE configurationparameter(s). The assistance information may inform the base stationthat the UE 404 would prefer to prioritize power savings overperformance, for example. When a user switches the UE 404 to a lowerpower mode, which will be followed by the UE component's including themodem, the UE 404 may indicate to the base station a preference forpower savings over performance in the UE's radio configurations. Aswell, based on a power status of the UE 404, the UE 404 may indicatepreferences to the base station 402 that will affect power savings. Aswell, the UE 404 may select the parameters based on a knowledge of whichapplications are active at the UE 404 and/or will become active at theUE 404.

The UE 404 may provide the assistance information to the base station,such as in an Information Element (IE). For example, the assistanceinformation may be included in a UE Assistance IE (UAI), e.g., inaddition to a UE's preferred setting for a delay budget report. Thedelay budget report may be used by the UE 404 to indicate a UE preferredadjustment to a connected mode DRX coverage enhancement configuration.

There may be various different parameters that a UE 404 may indicate tothe base station 402 in the assistance information, e.g. comprised inthe UAI. The UE 404 may send its preferred values of each of theparameters to the base station 402, e.g., in a single UAI. In anotherexample, the UE 404 may send a subset of the preferred parameters to thebase station 402 in a first UAI. The UE 404 may send another subset ofthe preferred parameters to the base station 402 in another UAI. The UE404 may send a single preferred parameter or indication to the basestation 402 in the UAI. Thus, the UE 404 may communicate assistanceinformation to the base station 402 in a grouping and order determinedby the UE 404.

The base station 402 may use the assistance information, at 411, todetermine the radio configurations for the UE 404. The assistanceinformation may be one of various factors considered by the base station402 in configuring the UE 404. The base station 402 might not beconstrained by the preferences indicated to the base station at 409, butmay be free to use the information to configure the UE 404 in a moreeffective manner. As well, the assistance information may indicate tothe base station 402 that the UE 404 would prefer to operate using alower power mode, and the base station 402 may determine the way toachieve the lower power mode through the UE's radio configurations. At413, the base station 402 may configure the UE 404 with theconfiguration(s) determined at 411 using the assistance informationprovided by the UE. The base station 402 and UE 404 may then implementthe configuration(s) in communicating with each other. As illustrated at415, the base station 402 may communicate uplink and/or downlinkcommunication with the UE 404 based on the configuration of the UE at413.

As illustrated at 403, the base station 402 may broadcast, or otherwisetransmit, a range of available parameters for UE selection. For example,rather than broadcasting the range of available parameters, the basestation 402 may indicate range(s) of available parameter(s) to the UE404 in dedicated RRC signaling for the UE 404. Thus, the base station402 may indicate to the UE 404 the ranges that are possible and/orwhether the base station 402 supports the UE selection of preferredradio configuration parameters. The network may determine whether tobroadcast the available ranges and may also determine which availableranges to broadcast. For example, a base station 402 may broadcastvalues of all potential parameters or only a subset of the potentialparameters. When a base station 402 does not broadcast the availablerange(s), it may indicate to the UE 404 that UE selection from amongthose parameter is not supported by the base station 402. Thus, at 405,the UE 404 may determine whether or not UE selection/recommendation ofassistance information is supported by the base station 402 based onwhether or not the UE 404 receives an indication of the range(s) ofavailable parameter(s) from the base station. When the UE 404 does notreceive any range(s) of available parameter(s) from the base station402, the UE 404 may determine that the UE does not support the UEselection of preferred parameter values. Thus, the UE 404 may refrainfrom selecting preferred values and may refrain from sending assistanceinformation to the base station 402.

If the UE 404 receives the range(s) of available parameter(s) from thebase station 402, at 403, the UE may select, at 407, a value from amongthe available ranges indicated by the base station 402. Thus, the UE 404may send back to the base station 402, in the assistance information409, an indication of a value/parameter selected from among the range ofavailable parameter(s) broadcast by the base station 402. The UE 404 mayuse an index comprised in a message to the base station 402 to indicatethe selected value from within the available range(s). For example, theindex may be comprised in a UAI. The UE 404 may send back an index foreach parameter for which the base station 402 provided an availablerange. The UE 404 may send back indexes for a subset of parameters forwhich the base station 402 provided available ranges. The UE 404 mayeven send back an index for a single parameter from among the parametersfor which the base station 402 provided available ranges. The UE 404 maydetermine for which parameters from a plurality of possible parameters,the UE 404 will provide assistance information to the base station 402.

The assistance information 409 provided by the UE 404 to the basestation 402 may comprise preferences/recommendation regarding any ofvarious parameters that affect a UE's radio configuration(s). Forexample, the indicated parameters may comprise any combination ofparameters related to the UE's DRX configuration, parameters related tothe UE's bandwidth configuration, parameters related to a data channelsfor the UE 404, parameters related to a control channel for the UE 404,parameters related to beam management for the UE 404, and/or parametersrelated to the UE's power status.

For example, the indicated parameters may comprise any combination ofparameters related to the UE's DRX configuration, such as a DRX onduration, a DRX inactivity timer, a DRX long cycle, a DRX short cycle, aDRX short cycle timer, a DRX slot offset, an average data rate fortraffic for the UE 404, an average Transport Block (TB) size for trafficfor the UE 404, or an average burst duration for traffic for the UE 404,among other examples. Such parameters related to the UE's DRXconfiguration may be sent in addition to, or separately from, a delaybudget report that may indicate a UE preference to adjust to a connectedmode DRX or a coverage enhancement configuration. For example, the delaybudget report may indicate that the UE 404 would prefer to transition toa long DRX cycle. The assistance information presented herein mayprovide different/additional parameters relating to a UE's DRXconfiguration. For example, by providing information about preferencesor recommendations for the UE's DRX configuration, the UE 404 mayindicate to the base station 402 whether the UE 404 is prioritizingpower savings or performance. The base station 402 may then configurethe UE 404 for DRX, e.g., at 413, with an understanding of which aspectthe UE 404 considers more important at the time. The base station 402may use at least one of the indicated parameters in configuring the UE404 for DRX, or the base station 402 may adjust a DRX parameter based onthe assistance information from the UE 404.

As another example, the indicated parameters may comprise anycombination of parameters related to the UE's bandwidth configurations.For example, the UE may indicate to the base station a preference orrecommendation for aggregated bandwidth across all serving cells for theUE 404, such as for serving cells for different carrier types. The UE404 may indicate to the base station 402 a preferred or recommendednumber of downlink carriers and/or uplink carriers for the UE 404. TheUE 404 may indicate to the base station 402 a preference/recommendationabout a carrier type, e.g., for carrier selection between FR1 and FR2.The base station 402 may determine a bandwidth configuration for the UE404 using the indicated bandwidth preferences from the UE 404. The basestation 402 may use at least one of the indicated parameters in thebandwidth configuration for the UE 404, or the base station 402 mayadjust a parameter of the UE's bandwidth configuration based on theassistance information from the UE 404.

As another example, the indicated parameters may comprise anycombination of parameters related to a data channel for the UE, such asPUSCH and/or PDSCH for the UE 404. For example, the UE 404 may indicatea preference or recommendation about a maximum TB size that the UE 404can handle in PUSCH and/or PDSCH. The base station 402 may determine aconfiguration for the UE 404 for PUSCH/PDSCH based on the assistanceinformation provided by the UE 404, e.g., for communication based on aTB size that does not exceed the maximum indicated by the UE 404.

As another example, the indicated parameters may comprise anycombination of parameters related to a control channel for the UE 404,e.g., PDCCH for the UE 404. The UE 404 may indicate apreference/recommendation for a particular TDD pattern for PDCCH. The UE404 may indicate a preference/recommendation for a particularperiodicity for PDCCH monitoring. A higher monitoring periodicity mayrequire larger amounts of power at the UE 404. The UE 404 may indicate apreference/recommendation for HARQ feedback from the UE 404, e.g.,information about a HARQ processing timeline. The base station 402 maydetermine a configuration for the UE 404 for PDCCH based on theassistance information provided by the UE 404, e.g., by selecting theTDD pattern, monitoring periodicity, and/or HARQ parameters using theassistance information provided by the UE 404.

As another example, the indicated parameters may comprise anycombination of parameters related to beam management for the UE 404. Forexample, the UE 404 may indicate a preference/recommendation for anantenna panel at the UE 404 and/or the base station 402, e.g., anantenna panel or a subset of antenna panels from among a plurality ofpossible antenna panels. The UE 404 may indicate apreference/recommendation for mobility parameters for the UE 404. The UE404 may indicate information about the UE 404 that may be helpful to thebase station 402 in performing beam management. The UE 404 may provide atrajectory of movement of the UE 404 that may assist the base station402 in selecting beams to use to transmit and/or receive communicationwith the UE 404, e.g., as described in connection with 182 in FIG. 1.The base station 402 may determine beam management configurations basedon the assistance information provided by the UE 404, e.g., with beamselection using the assistance information from the UE 404 regardingantenna panel(s) and/or mobility parameters for the UE 404.

As another example, the indicated parameters may comprise anycombination of parameters related to the UE's power status. For example,the assistance information may indicate a battery level for the UE 404.The battery level may help the base station 402 to understand whetherbattery savings are important for the UE 404 when determining radioconfigurations for the UE 404. The assistance information may indicate amodem thermal level for the UE 404. If the modem has a temperature abovea certain level, the base station 402 may determine that the UE 404would benefit from a lower power mode that would decrease activity andthe UE's modem in order to help reduce the temperature of the modem. Theassistance information may indicate a power preference indication. Thismay enable the UE 404 to communicate a power preference to the basestation 402, e.g., whether the UE 404 prefers a normal mode or a lowerpower mode, using a binary indication. The base station 402 may use theUE's indication to determine whether to configure the UE 404 tocommunicate using lower power configuration parameters.

FIG. 5 is a flowchart 500 of a method of wireless communication. Themethod may be performed by a UE or a component of a UE (such as UE 104,350, 404, 950; the apparatus 602, 602′; the processing system 1114,which may include memory and which may be an entire UE 350 or acomponent of a UE 350, such as the TX processor 368, the RX processor356, and/or the controller/processor 359). Optional aspects areillustrated with a dashed line. The method enables more effectiveconfigurations for a UE by having the UE provide assistance informationto the base station that can be used by the base station to configuredthe UE.

At 508, the UE transmits at least one UE configuration parameter to abase station comprising at least one preferred parameter for a UEconfiguration, e.g., a described in connection with 409 in FIG. 4. Forexample, the UE configuration parameter may be transmitted, e.g., by theassistance information component 614 of the apparatus 602 in FIG. 6. TheUE configuration parameter(s) may be indicated by the UE in an IE to thebase station. For example, the UE configuration parameter(s) may beindicated in a UAI, e.g., in addition to a preferred setting for a delaybudget report that indicates whether the UE prefers a long DRX mode.

The UE configuration parameter(s) may comprise an indication for apreferred parameter for at least one of a DRX on duration, a DRXinactivity timer, a DRX long cycle, a DRX short cycle, a DRX short cycletimer, a DRX slot offset, an average data rate, an average transportblock size, or an average burst duration. For example, the UEconfiguration parameter(s) may comprise an indication for a preferredbandwidth configuration for the UE, e.g., indicating at least one of anaggregated bandwidth across serving cells for different types ofcarriers, a downlink/uplink bandwidth part index for a serving cell, anumber of uplink carriers, a number of downlink carriers. The UEconfiguration parameter(s) may comprise an indication for a preferreddata channel parameter, e.g., indicating a maximum transport block sizefor a downlink data channel or an uplink data channel. The UEconfiguration parameter(s) may comprise an indication for a preferredcontrol channel parameter, e.g., comprising at least one of a TDDpattern, a control channel monitoring periodicity, or a processingtimeline related to feedback processing. The UE configurationparameter(s) may comprise an indication for a beam management parameter,e.g., comprising at least one of a preferred antenna panel, a preferredbeam, information about a trajectory of the UE, or a mobility parameterfor the UE. The UE configuration parameter(s) may indicate power statusinformation for the UE, e.g., at least one of a battery level, a thermallevel of a modem, or an indication of a power preference for the UE.

At 510, the UE receives a configuration from the base station based, atleast in part, on the UE configuration parameter(s) transmitted to thebase station. The configuration may be received, for example, by theconfiguration component 616 of the apparatus 602 in FIG. 6. As describedin connection with FIG. 4, the UE configuration parameter(s) may informthe base station about preferred parameters at the UE, e.g., for a powersavings, for higher performance, etc. The base station may determine themanner in which the desired result will be achieved and may configurethe UE accordingly. The base station may use a particular parameterindicated in the UE configuration parameter(s) from the UE or may usethe UE configuration parameter(s) to determine/adjust an existingparameter determined by the base station. Thus, the network mayconfigure a set of parameters for a UE, and during operation, a UE maysuggest preferred values for the parameters.

As illustrated at 512, the UE may use the configuration from the basestation to communicate with the base station, e.g., to transmit uplinkcommunication and/or to receive downlink communication. For example, inthe apparatus 602 in FIG. 6, the uplink communication may be transmittedby the transmission component 606 using the configuration, or downlinkcommunication may be received by the reception component 604 using theconfiguration.

As illustrated at 502, the UE may receive a range of availableparameters from the base station, e.g., as described in connection with403. The range of available parameters may be received, e.g., by therange component 608 of the apparatus 602 in FIG. 6. The range ofavailable parameters may be received in a broadcast from the basestation. In another example, the range of available parameters may bereceived in a dedicated RRC signaling for the UE. The UE may then selecta parameter for the UE configuration parameter(s), at 506, from amongthe range of available parameters received from the base station, e.g.,as described in connection with 407 in FIG. 4. For example, theselection component 612 of the apparatus 602 in FIG. 6 may perform theselection. The UE configuration parameter(s) may comprise an indexcorresponding to a value selected from among the range of availableparameters received from the base station. In another example in whichthe UE does not receive a range of available parameter from the basestation, at 502, the selection of parameters, at 506, may be madeindependently by the UE or in another manner.

The broadcast, or other signaling, of ranges of available parametersfrom a base station may be used by the UE to determine whether the basestation supports UE selection of the parameters. Thus, at 504, the UEmay determine that UE indication of the UE configuration parameter(s) issupported by the base station based on receiving the range of availableparameters from the base station, e.g., as described in connection with405 in FIG. 4. For example, the determination component 610 of theapparatus 602 in FIG. 6 may perform the determination.

FIG. 6 is a conceptual data flow diagram 600 illustrating the data flowbetween different means/components in an example apparatus 602. Theapparatus may be a UE or a component of a UE in communication with abase station 650. The apparatus includes a reception component 604 thatreceives downlink communication from base station 650 and a transmissioncomponent 606 that transmits uplink communication to the base station650. The apparatus may include an assistance information component 614configured to transmit UE configuration parameter(s) to a base stationcomprising at least one preferred parameter for a UE configuration,e.g., in addition to a preferred setting for a delay budget report, asdescribed in connection with 409, 508. The apparatus may include aconfiguration component 616 configured to receive a configuration fromthe base station based, at least in part, on the UE configurationparameter(s) transmitted to the base station, as described in connectionwith 413, 510. The apparatus may include a range component 608configured to receive a range of available parameters from the basestation, e.g., as described in connection with 403, 502. The apparatusmay include a selection component 612 configured to select a parameterfor the UE configuration parameter(s) from among the range of availableparameters received from the base station, as described in connectionwith 407, 506. The apparatus may include a determination component 610configured to determine that UE indication of the UE configurationparameter(s) is supported by the base station based on receiving therange of available parameters from the base station, e.g., as describedin connection with 405, 504. The apparatus may communicate, using thereception component 604 and/or transmission component 606, based on theconfiguration received from the base station.

The apparatus 602 may include additional components that perform each ofthe blocks of the algorithm in the aforementioned flowchart of FIG. 5and aspects of the communication flow in FIG. 4. As such, each block inthe aforementioned flowchart of FIG. 5 and aspects of the communicationflow in FIG. 4 may be performed by a component and the apparatus 602 mayinclude one or more of those components. The components may be one ormore hardware components specifically configured to carry out the statedprocesses/algorithm, implemented by a processor configured to performthe stated processes/algorithm, stored within a computer-readable mediumfor implementation by a processor, or some combination thereof.

FIG. 7 is a diagram 700 illustrating an example of a hardwareimplementation for an apparatus 602′ employing a processing system 714.The processing system 714 may be implemented with a bus architecture,represented generally by the bus 724. The bus 724 may include any numberof interconnecting buses and bridges depending on the specificapplication of the processing system 714 and the overall designconstraints. The bus 724 links together various circuits including oneor more processors and/or hardware components, represented by theprocessor 704, the components 604, 606, 608, 610, 612, 613, 616, and thecomputer-readable medium/memory 706. The bus 724 may also link variousother circuits such as timing sources, peripherals, voltage regulators,and power management circuits, which are well known in the art, andtherefore, will not be described any further.

The processing system 714 may be coupled to a transceiver 710. Thetransceiver 710 is coupled to one or more antennas 720. The transceiver710 provides a means for communicating with various other apparatus overa transmission medium. The transceiver 710 receives a signal from theone or more antennas 720, extracts information from the received signal,and provides the extracted information to the processing system 714,specifically the reception component 604. In addition, the transceiver710 receives information from the processing system 714, specificallythe transmission component 606, and based on the received information,generates a signal to be applied to the one or more antennas 720. Theprocessing system 714 includes a processor 704 coupled to acomputer-readable medium/memory 706. The processor 704 is responsiblefor general processing, including the execution of software stored onthe computer-readable medium/memory 706. The software, when executed bythe processor 704, causes the processing system 714 to perform thevarious functions described supra for any particular apparatus. Thecomputer-readable medium/memory 706 may also be used for storing datathat is manipulated by the processor 704 when executing software. Theprocessing system 714 further includes at least one of the components604, 606, 608, 610, 612, 613, 616. The components may be softwarecomponents running in the processor 704, resident/stored in the computerreadable medium/memory 706, one or more hardware components coupled tothe processor 704, or some combination thereof. The processing system714 may be a component of the UE 350 and may include the memory 360and/or at least one of the TX processor 368, the RX processor 356, andthe controller/processor 359. Alternatively, the processing system 714may be the entire UE (e.g., see 350 of FIG. 3).

In one configuration, the apparatus 602/602′ for wireless communicationincludes means for transmitting at least one UE configuration parameterto a base station comprising at least one preferred parameter for a UEconfiguration, e.g., in addition to a preferred setting for a delaybudget report (e.g., at least assistance information component 614); andmeans for receiving a configuration from the base station based, atleast in part, on the UE configuration parameter(s)transmitted to thebase station (e.g., at least configuration component 616). The apparatusmay include means for receiving a range of available parameters from thebase station (e.g., at least range component 608). The apparatus mayinclude means for selecting a parameter for the UE configurationparameter(s) from among the range of available parameters received fromthe base station (e.g., at least selection component 612). The apparatusmay include means for determining that UE indication of the UEconfiguration parameter(s) is supported by the base station based onreceiving the range of available parameters from the base station (e.g.,at least determination component 610). The aforementioned means may beone or more of the aforementioned components of the apparatus 602 and/orthe processing system 714 of the apparatus 602′ configured to performthe functions recited by the aforementioned means. As described supra,the processing system 714 may include the TX Processor 368, the RXProcessor 356, and the controller/processor 359. As such, in oneconfiguration, the aforementioned means may be the TX Processor 368, theRX Processor 356, and the controller/processor 359 configured to performthe functions recited by the aforementioned means.

FIG. 8 is a flowchart 800 of a method of wireless communication. Themethod may be performed by a base station or a component of a basestation (e.g., base station 102, 180, 310, 402, 650, the apparatus 902,902′; the processing system 1014, which may include memory and which maybe an entire base station 310 or a component of a base station 310, suchas the TX processor 316, the RX processor 370, and/or thecontroller/processor 375) in communication with a UE. Optional aspectsare illustrated with a dashed line. The method enables more effectiveconfigurations for a UE by having the UE provide assistance information,e.g., including UE configuration parameter(s), to the base station thatcan be used by the base station to configured the UE.

At 804, the base station receives at least one UE configurationparameter from a UE, the UE configuration parameter(s) comprising atleast one preferred parameter for a UE configuration, e.g., a describedin connection with 409 in FIG. 4. The reception of the UE configurationparameter may be performed, for example, by the assistance informationcomponent 908 of the apparatus 902 in FIG. 9, for example. The UEconfiguration parameter(s) may be received by the base station in an IEfrom the UE. For example, the UE configuration parameter(s) may beindicated in a UAI, e.g., in addition to a preferred setting for a delaybudget report that indicates whether a UE prefers a long DRX mode.

The UE configuration parameter(s) may comprise an indication for apreferred parameter for at least one of a DRX on duration, a DRXinactivity timer, a DRX long cycle, a DRX short cycle, a DRX short cycletimer, a DRX slot offset, an average data rate, an average transportblock size, or an average burst duration. For example, the UEconfiguration parameter(s) may comprise an indication for a preferredbandwidth configuration for the UE, e.g., indicating at least one of anaggregated bandwidth across serving cells for different types ofcarriers, a downlink/uplink bandwidth part index for a serving cell, anumber of uplink carriers, a number of downlink carriers, or a carriertype. The UE configuration parameter(s) may comprise an indication for apreferred data channel parameter, e.g., indicating a maximum transportblock size for a downlink data channel or an uplink data channel. The UEconfiguration parameter(s) may comprise an indication for a preferredcontrol channel parameter, e.g., comprising at least one of a TDDpattern, a control channel monitoring periodicity, or a processingtimeline related to feedback processing. The UE configurationparameter(s) may comprise an indication for a beam management parameter,e.g., comprising at least one of a preferred antenna panel, a preferredbeam, information about a trajectory of the UE, or a mobility parameterfor the UE. The UE configuration parameter(s) may indicate power statusinformation for the UE, e.g., at least one of a battery level, a thermallevel of a modem, or an indication of a power preference for the UE.

At 806, the base station configures the UE based, at least in part, onthe UE configuration parameter(s) received from the UE. Theconfiguration may be performed, e.g., by the configuration component 910of the apparatus 902 in FIG. 9. As described in connection with FIG. 4,the UE configuration parameter(s) may inform the base station aboutpreferred parameters at the UE, e.g., for a power savings, for higherperformance, etc. The base station may determine the manner in which thedesired result will be achieved and may configure the UE accordingly.The base station may use a particular parameter indicated in the UEconfiguration parameter(s) from the UE or may use the UE configurationparameter(s) to determine/adjust an existing parameter determined by thebase station. Thus, the network may configure a set of parameters for aUE, and during operation, a UE may suggest preferred values for theparameters.

As illustrated at 808, the base station may use the UE's configurationto communicate with the UE, e.g., to transmit downlink communicationand/or to receive uplink communication. For example, in the apparatus902 in FIG. 9, the downlink communication may be transmitted by thetransmission component 906 using the configuration using the UE'sconfiguration, or uplink communication may be received by the receptioncomponent 604 using the UE's configuration.

As illustrated at 802, the UE may transmit a range of availableparameters from the base station, and the UE configuration parameter(s)may comprise a parameter selected from among the range of availableparameters received from the base station, e.g., as described inconnection with 403 and 407 in FIG. 4. The range of parameters may betransmitted, e.g., by the range component 912 of the apparatus 902 inFIG. 9. The range of available parameters may be broadcast from the basestation. In another example, the base station may indicate the range ofavailable parameters to the UE in dedicated RRC signaling for the UE.The UE configuration parameter(s) from the UE may comprise an indexcorresponding to a value selected from among the range of availableparameters transmitted from the base station, at 802. In another examplein which the base station does not transmit a range of availableparameter 802, the selection of parameters, at 506, may be madeindependently by the UE. The presence or absence of a broadcast ofranges of available parameters from a base station may indicate to theUE whether the base station supports UE selection of the parameters.
